Network Security Efficacy in the Age of Pervasive TLS Encryption
As encryption becomes increasingly pervasive, network security administrators can struggle to maintain an acceptable level of security efficacy.
To the Depth of TLS Invisibility and Beyond
Encrypted traffic is changing the threat landscape...Encryption technology enables greater privacy and security to communicate and transact business online. Mobile, cloud, and web applications rely on well-implemented encryption mechanisms, using keys
TLS 1.3 and Forward Secrecy: Count Us In, and Here’s Why
The damage a hacker can do after discovering a server’s private encryption key is about to shrink considerably. That’s thanks to important improvements in the coming Internet Engineering Task Force...
The Impact on Network Security Through Encrypted Protocols – QUIC
QUIC stands for Quick UDP Internet Connections, an experimental protocol designed and deployed by Google.
The impact on network security through encrypted protocols – TLS 1.3
This post is the second part of my series around the impact of encrypted protocols on network security. You can find the first article about HTTP/2 here: http://blogs.cisco.com/security/the-impact-on-network-security-through-encrypted-protocols-http2
The impact on network security through encrypted protocols – HTTP/2
This is the start of a planned series of posts around the impact that new protocols are making on the way many of us deal with network security today. The protocols we have been using on the internet, mainly TCP with HTTP 1.1, have shown that they
ETSI/IQC’s 4th Workshop on Quantum-Safe Cryptography
Quantum computers could break commonly used public key algorithms, which would affect cryptography used today. For that reason, there has been great attention on quantum safe crypto recently. We have blogged about it in numerous occasions [1], [2]
Where is my (intermediate) TLS certificate?
When dealing with TLS connections, it is important to understand how a client (in most cases this is a web browser) will be acting. Let’s quickly check some of the steps that are happening when a TLS connection is made. A web server will send its
